7 Claims.

This invention relates to improvements in caps for use on automobileradiators or gasoline tanks.

It is particularly the object of this invention to provide a cap adaptedto be applied either to a radiator or a gasoline tank, and which may beused either with or without an ornament.

It is especially the object of this invention to provide, in connectionwith a cap, a central boss or core supporting the elements thatconstitute the complete cap structure and to so form this core that itmay be used for supporting the cap upon a radiator spout or upon thegasoline tank of an automobile.

When the cap is used for gasoline tanks in order to provide thenecessary ventilation, an

opening is made through the boss into a casing formed at the outer endof the boss, and when the cap is used in connection with an ornament ascrew opening is made in the boss and by means of a screw which holdsthe elements of the cap structure together, an ornament may be supportedon top of the cap as a whole.

It may be readily seen from the foregoing that the purpose of thisinvention is to provide a cap adapted to be used on a radiator with orwithout an ornament, and one that may be used for closing the gasolinetank and at the same time providing the necessary ventilation for thetank.

These and other advantages will appear from the following descriptiontaken in connection with the drawings.

Referring to the drawings:

Figure 1 is a top plan view of the cap with the outer shell removed,showing the boss with a hole therein for the attachment of an ornament.

Figure 2 is a View showing the outer shell in section and the otherparts of the cap in side elevation.

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a bottom plan view with parts of the shell broken away.

Figure 5 is a section through the boss and the adjacent parts of the capstructure to show the boss as used for a radiator cap without anornamerit.

Figure 6 is a view similar to Figure 1, showing the boss formedwith avent hole therein.

Figure '7 is a view similar to Figure 2 but of the form shown in Figure6.

Figure 8 is a section on the line 8-8 of Figure 6.

Figure 9 is a bottom plan view of the form shown in Figure 6, the shellsbeing partly broken away.

Figure 10 is a section on the line 10--1O of Figure 8.

This apparatus consists essentially of an outer shell 1, an inner shell2, which has a hole 3 therein, a boss 4 fitting within the hole of theinner shell and constituting the main support for the apparatus, aclosure means, and means for looking the cap as a whole on a spout.

1931, Serial No. 513,193

The boss, which constitutes the central and supporting part of theapparatus, has on its outer end a plurality of flanges 5. The other endof the boss is reduced in size, as indicated by the numeral 6, and hasthereon a washer 7. Around this reduced part and fitting against thewasher '7 is a saucer-shaped disc 8, which is composed of metal and isresilient in nature and adapted to press a gasket 9 against the top ofthe filler spout. The gasket is made of any suitable material.

The end of the boss adjacent the parts 8 and 9 is square and has fittingover it a locking cup member 10, which has in the center thereof asquare hole to receive the square end of the boss. In the presentinstance parts of the walls of the cup are pressed out to formspout-engaging lugs 11. In the present instance two of these lugs areshown. Any number may be provided.

In order to hold the parts assembled on the boss the boss has providedtherein a hole 12, which receives a screw 13 the head of which engagesthe inside of the bottom of the cup locking member to hold this lockingmember on the boss. This hole may extend partly through the boss, asshown in Figure 5, in which case a screw with a short shank is used. Asshown in Figure 3 the boss has attached thereto by any suitable meansthe inner shell member. In the present instance this shell member isattached to the boss by means of rivets forming parts of the flanges 5.

After the inner shell has been placed in position on the boss the outershell, which is somewhat cup-shaped, may be slipped over the inner shellin frictional engagement therewith. On the other end of the boss fromthe two shells are the washer '7, the disc 8, the gasket 9 and thecupshaped locking member 10. The latter four parts are assembled on theboss and retained by means of the screw 13.

Whenever it is desired that an ornament be mounted on top of the outershell a hole may be provided entirely through the boss and through thecenter of the outer shell, for receiving the long shank of a screw whichextends through the boss, the outer shell and into an ornament 14, asshown in Figures 2 and 3. The parts shown in these figures are the sameas the parts shown in Figure 5 except that no ornament is used in theform shown in Figure 5, and in order 'that an ornament may be used ahole is bored entirely through the boss to receive the long shank screw13.

In the forms shown in Figures 6, 7, 8 and 9 the cap is adapted to beused in connection with a spout of a gasoline tank, and in order toadapt the cap member as a whole for use as a gaso= line tank closure theform shown in Figure 5 is modified by having a hollow screw 17 in placeof the solid screw shown in Figure 5, and extending in line with thehollow screw through the boss is a vent hole 18 which leads into a draingroove 19 in the upper, outer surface of the boss just beneath the outershell, and a baflie member 22 with a hole 23 fitted to cup 10.

In the inner shell around the boss is a trough 20, which has in thebottom thereof one or more vent holes 21 for the entrance of air or theescape of gases and other materials which accumulate in the casingformed by the inner and outer shells. The outer edges of these twoshells have corrugations 15 and 16, as shown in Figures 7 and 10. Theouter shell is adapted to fit over the inner shell and to be heldthereon by friction between the two. In order to operate the cap as awhole the outer shell is rotated thereby rotating the inner shell, andwith it the boss and the locking cup. As shown in Figure 10 thecorrugations in these two parts are interlocked.

It is obvious that by the use of a cap of this nature the only thingnecessary to convert the cap from an ordinary cap, such. as that shownin Figure 5, to one supporting an ornament is that the hole forreceiving the screw be extended entirely through the boss so that a longshank screw, such as that shown in Figures 2 and 3, may be used. Thisscrew has its threaded end forced into the end of the ornament, and inorder to convert the form of boss shown in Figure 5, to one for use inconnection with a cap for a gasoline tank, it is necessary to remove thescrew shown in Figure 5 and replace it by a screw such as that shown inFigure 8 and form in the boss a vent hole 18.

These parts are composed of suitable material, the boss being of suchmaterial that the necessary holes may be bored therein for convertingthe cap from one form to another. The cap may be easily converted froman ordinary cap, such as that shown in Figure 5, and from a gasolinetank cap, such as that shown in Figures 6, '7 and 8, to anornament-carrying cap such as that shown in Figures 1, 2 and 3.

This cap is adapted to be used on most any form of spout, but moreparticularly it is adapted to be used in connection with a filler spoutwhich has its upper edge turned in and down to form cam surfaces to beengaged by the parts 11 of the locking cup.

Whenever the cap is to be placed in position the locking cup is forcedwithin the upper end of the spout and the cap as a whole is turned sothat the parts 11 engaging cam surfaces force the parts 8 and 9 tofrictionally engage the upper surface of the spout to form a tight,close fit therewith, the parts 8 and 9 being adapted to rotate aroundthe boss while the parts 1, 2 and 10 move with the boss and are affixedthereto for operating purposes.

I desire to comprehend Within my invention such modifications as may beembraced within my claims and the scope of my invention.
